Woolly Mammoth to be Cloned

Well preserved bone marrow from a woolly mammoth has been recovered in Siberia. A team of Russian and Japanese scientists has announced that it will use it in an attempt to clone a woolly mammoth within five years.

I assume the technique does not always take. In the abstract you will see a link that suggests they failed in a previous attempt. I suppose they will have to make arrangements to have an elephant carry the fetus.
